The ancient Persian kitchen was known for its aromatic and exotic flavors. While they didn't have a built-in slushie machine, they had a refreshing drink called 'sherbet.' Sherbet was made by mixing fruit juices with water, sugar, and various herbs and spices. The Persians would chill this mixture by placing it in a container surrounded by ice or snow. The result was a cool and slightly slushie-like beverage that was enjoyed during hot summer days.
